Electric switch |
摘要 |
In a push-push switch a contact carrier is provided which carries a contact member movable to and from a position in which it touches two terminals. The contact carrier member is provided with a central ribbed boss movable in a channel defined by co-operating axially extending ribs, the lowermost surface of the boss being serrated to cause rotation of a rotatable member having arms which engage the serrations or movement thereof by the push-button. The arms, in one position can pass freely past the ribs, and in another position engage a stop surface on the ribs, thus retaining the contact carrier member in a lower position in which the switch is closed. A first spring biasses the rotatable member upwardly and a second spring biasses the contact carrier downwardly.
